Factor completely 3x3 − 3x2 − 18x.
3x(x + 3)(x + 2)
3x(x + 3)(x − 2)
3x(x − 3)(x + 2)
3x(x − 3)(x − 2)

bottom left

step-by-step explanation:

the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.

hope this !

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
